Ignore blank column and jump for next step

Ok

You must use an if_v2 to skip field

This is the code to fill field only if COL1 have a value, edit with your COL number and xpath, you must use it in every field that use COL of csv

{
      "Command": "if_v2",
      "Target": "${!COL1}.length > 0",
      "Value": ""
    },
    {
      "Command": "type",
      "Target": "xpath=//input[@name='name']",
      "Value": "${!COL1}"
    },
    {
      "Command": "end",
      "Target": "",
      "Value": ""
    },
